Nothing in the client prunes reader data today — no store filters against the
feed, knownGames only appends, metaFor renders a lane whose game is gone — so a
retired source, page or game leaves completion marks, streaks and hand-entered
events untouched. That was true by construction and pinned nowhere.
The load path is what makes it worth pinning. useCustom reads through
validRecords, which drops a record that fails its schema, and the survivors are
what the next write persists. A record that stops parsing is therefore not
hidden until someone notices — it is deleted from the device, permanently, by
the act of opening the app, with no server-side copy to recover it from.
Which makes CustomEvent.game being z.string() rather than GameId the whole
safety property, and it currently reads like validation someone forgot. Anyone
narrowing it to the enum would be tightening a schema and arming every future
game removal to erase reader data on next launch. The tests state the premise,
the survival, and that one unreadable neighbour still does not take the rest
down; the field says why it is loose.

The data layer for PRD F13, with no UI and no behaviour change yet.
src/shared/custom.ts defines the two key spaces, their schemas, and the
projection into what the views read. Two properties are the point of it:
- A reader's event id is random, not derived from their title. They can type a
scraped event's exact name and date, which under ${game}:${slug}:${date} is a
byte-identical key — one completion mark and one streak silently shared by two
events. Randomness also means renaming their own event never moves its id.
- A reader's event carries no sourceUrl, so a hand-entered date can never be
attributed to a source, and claims no region split, because they entered one
instant and inventing three would fabricate two of them.
The rest is widening what was GameId-shaped into a lane that may be one of
theirs: clockFor takes the boundary fields structurally so their events run on
the identical countdown rather than a second one, day keys fall back to the
regional default for a lane with no server map, and gameMeta becomes a context
resolver so metaFor stays pure and total — a lane can outlive its game when an
import carries an event whose game did not come with it.
